Dual-CPU home gateway and entertainment center

As the first ASUS N600 simultaneous dual-band Wi-Fi ADSL router, the DSL-N55U provides a stylish design, sophisticated features, and easy setup alongside supreme wireless and wired networking for the home.

Two USB 2.0 ports allow the DSL-N55U to share 3G/4G dongle signal; to share printing and scanning functions on a network, and operate as high-speed NAS (Network Attached Storage) when an external storage device is connected. It can act as a media server and home entertainment center. Any device, such as a PS3, iPhone, or Eee Pad can directly stream music and video wirelessly through the DSL-N55U.

For wired networking, four Gigabit Ethernet ports provide excellent capacity. Support for up to 300,000 data sessions means the DSL-N55U has around 20 times the networking capacity of other home routers. Data transmission stays fast even when the router is under heavy load, and easy-to-use QoS settings assure that important traffic — VoIP calls or online gaming — isn’t adversely affected by large file downloads.

Two Devices in One – ADSL Modem and Wi-Fi Router

Designed with the latest in networking technology, the DSL-N55U has two Independent CPUs for its ADSL modem and Wi-Fi router modes, which deliver exceptionally fast wired and wireless connectivity. It comes with a powerful detachable Wi-Fi antenna to further extend wireless range.

Dual-Band Connectivity for Lag-Free Entertainment

Double your total wireless bandwidth and reduce Wi-Fi interference with the DSL-N55U’s simultaneous 2.4GHz and 5GHz bands at a combined speed of up to 600Mbps. Basic internet processes like web browsing or file downloads run under the 2.4GHz band, while simultaneous streaming of HD content occurs in the super-fast 5GHz band, always ensuring optimized speeds and allowing a smooth and buffer-free experience.

3-Step Easy Setup Through Your Pad, Smartphone, or PC

You will be taken to a setup page with a prompt to enter the ID/password from your Internet provider and that’s it! Now setting up your network is easier than ever.

Optimize Your Network for You

Do you game a lot, or spend most of your time streaming videos? Whatever your planned use is, the DSL-N55U has a Quality of Service (QoS) that lets you select how much bandwidth is prioritized for virtually any task. Plus, the traffic monitor allows you to check your Web usage in a clear and graphical interface.

ASUS offers a true wonder of ease of use, and puts fast networking speeds
within your reach quicker than ever before.

Dual Purpose: 3G/4G and WAN

VPN Server Enabled

Easily set up a VPN server to browse the web and
access data with MPPE encryption— wherever you are.

Two Multi-Functional Built-In USB ports

Featuring connectivity to devices, FTPs, Samba, UPnP AV servers, the DSL-N55U makes sharing and networking easier with two built-in USB ports. Download HTTP, FTP, and P2P files to a router-connected USB storage device all day, even without a PC. Additionally, the twin USB ports allow for networked printer and file server connections, so you perform multiple tasks at once.

Powerful Online Multitasking at up to 300,000 Data Sessions

Support for a massive data pipeline of up to 300,000 data sessions means the DSL-N55U has around 20 times the networking capacity of conventional routers for exceptionally smooth performance.
